MAX16930AGLR/VY+

DC DC Switching Controllers Overview

The MAX16930AGLR/VY+ is a dual synchronous step-down DC-DC controller from Analog Devices, designed for high-efficiency power conversion. It features an integrated preboost regulator to ensure optimal gate drive performance across the input voltage range. The device operates with a fixed switching frequency of 2 MHz and supports input voltages from 3.5 V to 36 V. It provides two independent output channels capable of delivering up to 20 A of current each. The controller includes comprehensive protection features such as overcurrent protection, thermal shutdown, and soft-start functionality. Packaged in a 40-pin QFN exposed pad, it is suitable for industrial and telecom applications requiring compact, high-power solutions.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'VY+' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 40-QFN package. Check for obsolescence notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring dual isolated or non-isolated outputs from a single wide-range input. Consider the 2 MHz frequency for balancing size and efficiency. Evaluate thermal requirements based on the expected load current and ambient conditions. Ensure the control loop compensation network is properly designed for stability under varying load conditions.

DC DC Switching Controllers Part Context

The MAX16930 belongs to Maxim Integrated's family of high-performance synchronous buck controllers. It is engineered for applications demanding high power density and reliability. The AG variant typically denotes automotive-grade qualification, aligning with AEC-Q100 standards for robustness in demanding environments.

DC DC Switching Controllers Replacement Considerations

Direct replacements may include other dual-channel buck controllers from Analog Devices with similar pinouts and electrical characteristics. Verify that any substitute matches the 2 MHz frequency, input voltage range, and current capabilities. Cross-reference pin assignments and thermal pad configurations to ensure mechanical compatibility.
